Title: Superconducting magnetic detecting device
Inventor: KATAOKA TERUYUKI
IPC: G01R33/09
Filed: 1995-03-24
Abstract: PURPOSE: To obtain a magnetic detection sensitivity of 10<-9> gausses or thereabouts or higher by a method wherein a second super-conducting magnetoresistance element, which is actuated by a current generated according to the intensity of a magnetic field detected by a first superconducting magnetoresistive element, is provided. CONSTITUTION: Two kinds of coils 2 and 3 for modulated magnetic field generation are provided on the periphery of a superconducting ceramic magnetoresistive element 1 for magnetic field measurement with a Dewar 18 between them, currents of frequencies different from each other are respectively fed to these coils by two oscillators 5 and 6 through resistors 16 and 17 and a double modulated magnetic field is generated in the coils. When the magnetic field being measured is changed, the currents are also changed according to the change of the magnetic field. This changed current is applied to a current terminal of a superconducting ceramic magnetoresistance element 14 for sensitivity characteristic improvement.  Whereupon, a magnetoelectric conversion point is moved into the shape of the magnetoelectric conversion curve of a current value to correspond to the magnitude of a magnetic field detected by the element 1 to steepen the magnetoelectric conversion curve and a magnetic detection sensitivity of 10<-9> gausses or thereabouts or higher can be obtained.

Abstract: PURPOSE: To ultrafilter waste liquid containing boric acid, treat the filtrate with an ion exchange resin and recover the treated liquid as a primary coolant.  
     CONSTITUTION: The boric-acid-containing waste liquid from a nuclear power plant is conveyed from a storage tank 1 to a circulation tank 3 by a pump 2. The waste liquid is removed of suspended substances by a filter 5 in the circulation tank 3 and then transferred to an ultrafilter module 6. The concentrated suspension separated by the ultrafilter module 6 is returned to the circulation tank 3. The filtrate separated by the module 6 is temporarily stored in a tank 7 and then conducted to an ion exchange resin column 9 by pump 8. The filtrate is removed of ionic impurities by the column 9. Since the liquid drained from the ion exchange resin column 9 contains pure boric acid, the liquid is used again as the primary coolant. The suspended substances concentrated by the ultrafilter module 6 are concentrated further by an evaporator 11 and thereafter solidified with cement or the like.

Abstract: PURPOSE:To manufacture the grain-oriented silicon steel sheet excellent in the magnetic property in an industrially stable manner by respectively prescribing the atmospheric gases for the secondary re-crystallization annealing and the purging annealing in the finish annealing of the grain-oriented silicon steel sheet containing Si of a specific amount. CONSTITUTION:The grain-oriented silicon steel sheet containing 0.8-6.8wt.% Si is hot rolled, and then, cold rolled. This cold-rolled steel sheet is primary re-crystalfization annealed in common with the decarburization. The steel sheet is nitrided to form and increase the nitride as the inhibitor. One or more kinds of At, Ti, V, Nb, Zr, Ta and Cr is preferably used as the element to form the nitride contained in the steel sheet. Then, the separation agent for annealing is coated on this decarburization annealed steel sheet to perform the finish annealing. The atmospheric gas for the finish annealing is the nitrogen gas or the mixed gas containing nitrogen during the secondary re-crystallization annealing, and the partial pressure of nitrogen is controlled to be reduced continuously or step by step, and the purifying annealing is performed in the hydrogen atmosphere. This constitution controls the formation of the nitride, stabilizes the secondary re-crystallization, and obtains the grain-oriented silicon steel sheet with high magnetic flux density.
